BACKGROUND OF THE INVENTION

Handheld devices such as personal digital assistants (PDAs), and cell phones have entered the market successfully in North America and overseas. These carrier-based solutions are constantly expanding to include more features that deliver useful content (news, entertainment, and data) to the user. Unfortunately, carrier based systems are bogged down by high traffic and low data transfer rates and furthermore are billed at extremely high rates. Though in some cases they provide real-time delivery of content, the average user does not always require this. The average user who does not need real-time content delivery (such as real time delivery of email) currently does not have the ability to scale down the carrier-based services and is therefore stuck paying expensive recurring service bills along with the one-time cost of their device.

The proposed invention describes a distributed network comprised of nodes equipped with wireless transceivers. The distributed network itself may be formed by connecting each node to the internet or any other existing or new network infrastructure such that the terminals are able to transmit data to and from each other as the existing nodes presently do. The wireless transceivers on each network node expand the range of the newly formed network to wireless devices in the physical coverage area. Therefore, a wireless connection is provided for any wireless-equipped device within the physical range of a terminal to connect to the network. Using this type of network between terminals allows rapid content delivery or reception to and from any device equipped with the required wireless connectivity hardware.

Content delivery is performed at “terminal” locations without the need of physically connecting a wire to the network. The client devices are also equipped with wireless connectivity hardware communicate with the distributed network via the wireless connection (when physically in range). Conversely, the user may transmit data wirelessly to the terminal for use anywhere on the wired network or storage.

SUMMARY OF THE INVENTION

A wireless distribution network for content delivery and data collection to and from portable devices is provided by the present invention. The network is based around a wide-area network WAN , such as the internet, connecting a server controlling access to content storage by home nodes, service center nodes and a plurality of wireless nodes. The server is at a first location. A plurality of the wireless nodes are disposed at a plurality of locations, such as gas stations (vehicle service stations). The plurality of wireless nodes are connected to the server via the network.

Each wireless node is capable of transferring information wirelessly between the node and one of a plurality of portable devices. Each node is capable of detecting and identifying each of the plurality of portable devices. Each node transfers information between the node and the plurality of portable devices based upon the detection and identification of the portable devices. The node also transfers the information between the node and the first computer based upon the detection and identification of the portable devices.

In this manner, an efficient, simple system for transferring information between the portable devices and a server is provided.

BRIEF DESCRIPTION OF THE DRAWINGS

Other advantages of the present invention can be understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:

FIG. 1 schematically illustrates the distribution network according to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A wireless distribution network 20 for content delivery and data collection to and from portable devices 60 is shown schematically in FIG. 1. The network 20 is based around a wide-area network WAN 22, such as the internet, connecting a server 24 (which may comprise a group of servers) controlling access to content storage 26 by home nodes 28 (one shown), service center nodes 30 (one shown) and a plurality of wireless nodes 36.

Each wireless node 36 is connected to the WAN 22 at its location 40. The locations 40 are preferably gas stations because vehicles travel to and stop at gas stations on a fairly regular basis. Even during long trips away from home, the vehicle must stop at gas stations 40 periodically during which time information may be exchanged between the portable device 60 and the server 26.

The wireless node 36 includes a processor 42 and associated memory, software and hardware to perform the functions described herein. Storage 44, such as a hard drive and/or optical or other media is provided at each wireless node 36. The storage 44 includes identification of the specific wireless node 36 on which it is located, including the location of the wireless node 36. The storage 44 may also include specific, locally-relevant data such as maps of the surrounding area, available hotels, restaurants, etc. specific to the location 40 and surrounding area. The storage 44 may also include advertising to be displayed, played or otherwise presented to the user on the portable device 60. The fees for the advertising may assist in defraying the cost of the system or the service for the user. The advertising could be geographically specific, such that each wireless node 36 stores at least some advertising that is specific to the surrounding geographic area of its location 40.

The wireless node 36 further includes a transceiver 38 for creating a wireless access point to the WAN 22. The transceiver 38 may use known wireless network communication standards such as 802.11, but preferably uses Bluetooth. The Bluetooth connection is secure and has a limited range, which effectively limits the use of the wireless node 36 to the location 40, which in this example is a gas station 40.

A plurality of portable devices 60 each include a processor 62, storage 64 and input/output devices 68. The storage 64 can be memory and/or a hard drive or other storage media. The portable devices 60 further each include a transceiver 70 complementary to the transceiver 38 at each wireless node 36. The portable device 60 may be installed in a vehicle 60 a, or may be a portable computer 60 b, or cell phone/PDA 60 c, but in this example the portable device 60 will be described as installed in a vehicle 60 a. It is expected that multiple types of devices, such as computers 60 b, cellphone/PDAs 60 c, etc would be able to connect to the network 20. In a vehicle 60 a, the device 60 could be integrated with the vehicle's entertainment system, navigation systems, email system and other vehicle information systems.

The home node 28 includes a home computer 72 connected to the WAN 22 and able to access the server 24 via the WAN 22.

In use, on the display 74 of the computer 72, the user can choose from various content 78 stored on server storage 26, such as audio content (mp3s or other compressed audio formats), local area maps, car-tones, ring-tones, advertising, coupons, email or movies for an in-vehicle entertainment system. The user chooses from among the content 78, such as by dragging the content 78 to a vehicle icon 80 on the display 74. The user logs into the server 24 via the home computer 72 and WAN 22 by entering a user id 82 and password 84. A credit card associated with the account is charged for the content 78 selected by the user. The account is also associated with a specific portable device 60 (e.g a specific vehicle 60 a), or a plurality of specific portable devices 60, owned by the user.

When the portable device 60 comes within range of one of the wireless nodes 36, the wireless node 36 identifies the specific portable device 60 via wireless communication via transceivers 38, 70, and by referencing the server 24 via the WAN 22. The wireless node 36 then determines whether there is any content 78 waiting to be downloaded to the portable device 60. If so, the content 78 is downloaded to the storage 44 on the wireless node 36 and then transferred to the storage 64 on the portable device 60 via transceivers 38, 70. Again, Bluetooth is preferred and has identification and transfer standards that would be followed.

Additionally, the wireless node 36 determines whether there is any information to be uploaded from the portable device 60 to the server 24. For example, the portable device 60 may temporarily store email/SMS to be sent, vehicle usage data, a vehicle ID (for non real-time tracking) and financial transaction data in storage 64. The vehicle usage data may include information relevant to pay-as-you-drive vehicle insurance arrangements, such as the locations the vehicle has been driven, the distance the vehicle has driven, the speed the vehicle has driven, etc. This data in particular does not need to be transferred on a real-time basis. Periodic updates are sufficient.

Each location 40 may also include a service center 30, which is a public computer connected to the server 24 via the WAN 22. At the service center 30, the user can log into their account and make additional selections of content 78 or adjust other preferences and settings for their account. This content 78 may be downloaded to the vehicle 60 a by the wireless node 36 at that location 40 before the user leaves the location 40.

In accordance with the provisions of the patent statutes and jurisprudence, exemplary configurations described above are considered to represent a preferred embodiment of the invention. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.
